When materials need to sterilization sterilization pot, hot water tank of hot water into the sterilization pot after pot of hot water into the sterilization and pressure in the hot water circulating pump cycle under the effect of steam heating.

When sterilized pot materials need to be sterilized, hot water tanks will be injected into the hot pot, which kill bacteria in hot water after pot germicidal into hot water circulating pump and pressure vapor under the role warming cycle.

When in the sterilization pot the material needs to sterilize, pours into the thermal flask in hot water the sterilization pot, after the hot water enters the sterilization pot circulates the elevation of temperature in the hot water circulating pump and under the pressure steam function.

When sterilization pot material when sterilization is required, bring hot water tank water into the retorts, hot water upon entering the retorts in hot water subjected to cyclic pump and pressure steam cycle heat up.

When materials need to sterilization sterilization pot, hot water tank of hot water into the sterilization pot after pot of hot water into the sterilization and pressure in the hot water circulating pump cycle under the effect of steam heating.
